An NGear came stock on my 1x El Mariachi. I added an outer bash ring and it's been golden. No chain drop. Ever. I've been tempted by the MRP, E13 and other 1x chain retention devices but why mess with what works?

Yep, good performance here as well with a bash and ngear. When new, I had to tighten the clamp bolt a few times before everything settled in. That was the only time I dropped a chain due the the bolt being loose and the keeper slid in.
